ATAG_Lewis took the Beaufighter out for a test flight during beta v4.49 as Team Fusion Simulations work through correcting the final bugs before releasing v4.5 on Steam.
This video shows nearly 50-minutes of footage as he takes the beast into the air of IL2 Cliffs of Dover.

Couple of points to note. This is beta testing and features are being added and removed (bugs that is) so this video while representative of beta testing is not guaranteed to show everything that will be available on final release.

Next, beta testing of the enamy Ai gunners. TFS are currently running varios server missions to test and change the effectiveness of the enemy Ai at different difficulty settings from Rookie to Ace. The Do-17's shown in this footage are before those tweaks were made and are too accurate....although sitting on the six o'clock of five bombers is likely to always be a world of hurt!
